Veronica plant named ‘Blue Bomb’

ABSTRACT

A  Veronica  plant particularly distinguished by a compact, well-branched plant habit, strong stems, strongly-branched, compact inflorescences, a very floriferous blooming habit with re-blooming and easy to grow a strong and well-developed plant in one season, is disclosed.

Genus and species; Veronica sp.

Variety denomination: ‘Blue Bomb’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Veronica, botanically known as Veronica sp., and hereinafter referred to by the variety name ‘Blue Bomb’. ‘Blue Bomb’ was developed through a cross conducted in the summer of 2006 between the female, an un-named proprietary Veronica sp. seedling (unpatented) and the male parent, an un-named proprietary Veronica sp. seedling (unpatented) in Haarlem, The Netherlands. ‘Blue Bomb’ was selected as a single plant in June 2007 and was first propagated in summer 2007 via softwood cuttings in Haarlem, The Netherlands.

‘Blue Bomb’ has been propagated for approximately 4 generations via softwood cuttings and has been found to retain its distinctive characteristics through successive asexual propagations via softwood cuttings.

Plant Breeder's Rights for this variety have not been applied for. ‘Blue Bomb’ has not been made publicly available or sold more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Haarlem, The Netherlands.

-   -   1. A compact, well-branched plant habit;     -   2. Strong stems;     -   3. Strongly-branched, compact inflorescences;     -   4. A very floriferous blooming habit with re-blooming; and     -   5. Easy to grow a strong and well-developed plant in one season.

DESCRIPTION OF THE PHOTOGRAPHS

This new Veronica plant is illustrated by the accompanying photographs which show blooms, buds, and foliage of the plant in full color; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of two-year-old plants grown in Haarlem, The Netherlands in July 2010.

FIG. 1 shows a whole plant, including leaves, buds and inflorescence.

FIG. 3 shows a close-up of a mature leaf.

FIG. 2 shows a close-up of the inflorescence.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Blue Bomb’. The data which define these characteristics were collected from asexual reproductions carried out in Haarlem, The Netherlands. The plant history was taken on two-year-old plants grown outdoors in Haarlem, The Netherlands in July 2010. Color readings were taken under natural light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2007 edition).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETY

‘Blue Bomb’ differs from the female parent, a proprietary un-named Veronica plant (unpatented) in that ‘Blue Bomb’ has more strongly branched and compact inflorescences and a darker blue inflorescence color than the female parent.

The male parent of ‘Blue Bomb’ is no longer available for comparison.

‘Blue Bomb’ differs from the commercial variety ‘Sunny Border Blue’ (unpatented) in that ‘Blue Bomb’ has a compact, well-branched plant habit, strong stems, strongly branched inflorescences and re-blooming, while ‘Sunny Border Blue’ has a less compact and branched habit, weaker stems, less branched inflorescences and does not re-bloom. 

I claim:
 1. A new and distinct variety of Veronica plant as described and shown herein.
